Dissertation Research: Quantifying Stopover Habitat use by Forest Dwelling Migratory Landbirds using Doppler Radar

[00:73114] larkin鸟类迁徙过程中至关重要的栖息地很少得到保护和研究。本研究旨在探讨中途停留生境分布对候鸟密度格局的影响。一个全国性的多普勒监视雷达网络将用于估计鸟类密度，并在大陆、区域和景观尺度上检查栖息地-候鸟关系。利用层次分析，在一个尺度上观察到的移民密度变化模式将允许对相邻尺度的模式进行可验证的预测。野外雷达研究将用于将高空鸟类密度与这些鸟类返回的雷达回波量联系起来。这种分级方法可以为候鸟保护区的确定提供适当的尺度依据。

0073114LarkinHabitat critical to birds during migration has received little conservation and research attention. This research project investigates the spatial scales at which the distribution of stopover habitat influences patterns of migrating bird density. A national network of Doppler surveillance radar will be used to estimate bird density and examine habitat-migrant associations within continental, regional, and landscape scales. Using hierarchical analysis, patterns of variation in migrant density observed at one scale will allow verifiable predictions about patterns at adjacent scales. Field radar studies will be used to relate bird density aloft and the amount of radar echo returned by those birds. This hierarchical approach can provide an appropriately scaled basis for identifying conservation areas for migratory birds.
